.Dd May 21, 1999 .Dt ATKBD 4 .Os FreeBSD .Sh NAME .Nm atkbd .Nd the AT keyboard interface .Sh SYNOPSIS .Cd "options ATKBD_DFLT_KEYMAP" .Cd "makeoptions ATKBD_DFLT_KEYMAP"="_keymap_name_" .Cd "options KBD_DISABLE_KEYMAP_LOAD" .Cd "device atkbd0 at atkbdc? irq 1" .Sh DESCRIPTION The .Nm driver, together with the .Nm atkbdc driver, provides access to the AT 84 keyboard or the AT enhanced keyboard which is connected to the AT keyboard controller.
p This driver is required for the console drivers .Xr syscons 4 and .Xr pcvt 4 .
p There can be only one .Nm device defined in the kernel configuration file. This device also requires the .Nm atkbdc keyboard controller to be present. The .Em irq number must always be 1; there is no provision of changing the number. .Ss Function Keys The AT keyboard has a number of function keys. They are numbered as follows and can be associated with strings by the .Xr kbdcontrol 1 command.

p See the man page for the .Xr kbdcontrol 1 command for how to assign a string to the function key. .Sh DRIVER CONFIGURATION .Ss Kernel Configuration Options The following kernel configuration options control the .Nm driver. l -tag -width ATKBD_DFLT t Em ATKBD_DFLT_KEYMAP This option sets the defauilt, built-in keymap of the .Nm driver to the named keymap. See .Sx EXAMPLE below. t Em KBD_DISABLE_KEYMAP_LOAD The keymap can be modified by the .Xr kbdcontrol 1 command. This option will disable this feature and prevent the user from changing key assignment. .El
p .Ss Driver Flags The .Nm driver accepts the following driver flags. They can be set either in the kernel configuration file
q see Xr config 8 , or else in the User Configuration Menu at boot time
q see Xr boot 8 .
l -tag -width FAIL t bit 0 (FAIL_IF_NO_KBD) By default the
.Nm
driver will install even if a keyboard is not actually connected to the
system.
This option prevents the driver from being installed in this situation.
t bit 1 (NO_RESET) When this option is given, the
.Nm
driver will not reset the keyboard when initializing it.
It may be useful for laptop computers whose function keys
have special functions and these functions are forgotten when the
keyboard is reset.
t bit 2 (ALT_SCANCODESET) Certain keyboards, such as those on some ThinkPad models, behave
like the old XT keyboard and require this option.
.El
.Sh FILES
.Sh EXAMPLE
The
.Nm
driver requires the keyboard controller
.Nm atkbdc .
Thus, the kernel configuration file should contain the following lines.
p .Dl "device atkbdc0 at isa" .Dl "device atkbd0 at atkbdc? irq 1"
p The following example shows how to set the default, built-in keymap to
a jp.106.kbd .
p .Dl "options ATKBD_DFLT_KEYMAP" .Dl "makeoptions ATKBD_DFLT_KEYMAP"="jp.106" .Dl "device atkbd0 at atkbdc? irq 1"
